Association of miR-155, miR-187 and Inflammatory Cytokines IL-6, IL-10 and TNF-α in Chronic Opium Abusers.
Article in Inflammation, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 15 papers, 1 of them a synthesis that pooled it.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Substance use disorders are known to be associated with inflammation. However, the dynamics of inflammatory cytokines and microRNA in chronic opium use is yet unexplored. The current study determined the levels of inflammatory cytokines TNF-α, IL-6, IL-10 and immune-regulatory miR-155 and miR-187 expressions in chronic opioid use disorder. Adults (n = 48) meeting the 5th Edition of the DSM criteria regarding opioid use disorder and healthy controls (n = 46) were included in the study. Inflammatory cytokines IL-10, IL-6, and TNF-α were analyzed from serum samples, and peripheral blood mononuclear cells processed for miRNA expression. Cases showed significantly raised IL-10 and TNF-α and reduced IL-6. Dose-dependent upregulation of miR-155-5p and miR-187-5p was evident at opium dose >1500 g/month, with a corresponding increase of TNF-α and IL-10. MiR-155 showed a significant positive correlation with IL-6 and TNF-α levels, while miR-187 showed a significant negative association with TNF-α at ≥1000 g/month consumption. Therefore, increasing consumption of opium probably enhances inflammation leading to immunomodulation and aberrant expression of hsa-miR-155-5p and hsa-miR-187-5p in opioid use disorder.
